I get the question, "What should I dress my baby in at night?" a lot. Therefore, I've made a handy chart for you to refer to if you're just not sure. This chart was created for children who wear a sleepsack to bed [which I recommend for all babies and children alike!] but the same idea can be applied to children who are not wearing a sleepsack or who are swaddled. The recommended temperature for baby's room, in order to provide the optimal environment for good-quality sleep, is between 19-21°C [68-72°F].
